A particulate material spreader includes an adjustable spinner apparatus which is incrementally adjustable forwardly and rearwardly to a plurality of operating positions relative to the discharge end of the material conveyor. The adjustment may be manual or automatic to adjust the drop point of the material onto the spinners, thereby accommodating varying application rates of the particulate material on a field, lawn, road, or other area. The spreader may be operatively connected to a microprocessor to receive data input and sensor feedback for variable rate technology.
